list - Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 3, Size: 2 -


still have problem java :/ here problem list :

if(listkey.size() == 1){         k = listkey.get(0); }else if(listkey.size() > 1){         for(int q : listkey){             if(listkey.get(q) == listkey.size()){                 k = listkey.get(0);                 k1 = listkey.get(1);             }             else if(listkey.get(q) == listkey.size() -1 ){                 k = listkey.get(q+1);                 k1 = listkey.get(0);              }             else if(listkey.get(q) == key && listkey.get(q) != listkey.size()){                 k = listkey.get(q+1);                 k1 = listkey.get(q+2);              }         }   }else if(listkey.size() == 0){         system.out.println("empty");     }

it gives me error:

exception in thread "main" java.lang.indexoutofboundsexception: index: 3, size: 2 @ java.util.arraylist.rangecheck(arraylist.java:635) @ java.util.arraylist.get(arraylist.java:411) @ com.server.peernode.findreplicas(peernode.java:222) @ com.server.peernode.printmenu(peernode.java:154) @ com.server.peernode.run(peernode.java:99) @ com.server.main.main(main.java:64)

i think i'm using correctly list , how iterate through it! i'm not exceeding size of list when try int it. in advance help

here idea: got key = 5   case 1: array {4}... want put 4 k case 2: array {4,6}.. want put k=6 , k1=4 case 3: array {4,6,7}.. want put k=6 , k1=7

i know mess code... , erros. hugh fixed , works... it's now:

    if(listkey.size() == 1){         keyreplica1 = listkey.get(0);      }else if(listkey.size() > 1){         listkey.add(key);         collections.sort(listkey);         (int q=0; q<listkey.size(); q++){             if(listkey.get(q) == key && listkey.get(q) == listkey.size()){                 keyreplica1 = listkey.get(0);                 keyreplica2 = listkey.get(1);              }             else if(listkey.get(q) == key && listkey.get(q) == listkey.size() -1 ){                 keyreplica1 = listkey.get(q+1);                 keyreplica2 = listkey.get(0);              }             else if(listkey.get(q) == key && listkey.get(q) != listkey.size()){                 keyreplica1 = listkey.get(q+1);                 keyreplica2 = listkey.get(q+2);              }         }      }else if(listkey.size() == 0){      }

is listkey list of integer? think you're mixing keys , values here - if list has more 1 entry, loop on values v, try v-th value in list. example, if listkey {3,4}, attempt find 3rd value in list, exceed bounds.

i think using following loop instead give behaviour expect:

for (int q=0; q<listkeys.size(); q++){
